IPC: E05B15/02
Filed: 1994-11-16
Abstract: An alarm-triggering locking mechanism for the lock and/or hinge area of a door to be secured or a window to be secured is proposed, which is embodied as a locking plate (23) which can be attached to a door or window frame by means of holding screws (27) embodied as the first blocking device. A second blocking device, which is harder to overcome by the effect of force, is embodied as at least one striker element (25) rigidly connected with the locking plate (23) and which, following the limited movement of the locking plate (23) in the opening direction, comes to rest against a counter-striker element (26) anchored on the door or window frame. An alarm, in particular a silent alarm, is triggered via radio or the telephone net after the first blocking device has been overcome. The burglar is thereafter delayed by the second blocking device, which makes it possible for security forces to reach the location of the break-in and to arrest the burglar while the break-in is still in progress.

Title: Ion beam process for deposition of highly abrasion-resistant coatings
Inventor: KNAPP BRADLEY J
IPC: C23C14/46
Filed: 1995-03-01
Abstract: An ion beam deposition method is provided for manufacturing a coated sub-strate with improved abrasion resistance, and improved lifetime. The substrate is first chemically cleaned to remove con-taminants. Secondly, the substrate is in-serted into a vacuum chamber (1) on holder (3), and the air therein is evacuated via pump (2).  Then the substrate surface is bombarded with energetic ions from ion beam source (4) supplied from inert (5) or reactive (6) gas inlets to assist in re-moving residual hydrocarbons and surface oxides, and activating the surface.  After sputter-etching the surface, a protective, abrasion-resistant coating is deposited by ion beam deposition where reactive gas in-lets (7, 8 and 9) may be employed.  The ion beam-deposited coating may contain one or more layers.  Once the chosen coat-ing thickness is achieved, deposition is ter-minated, vacuum chamber pressure is in-creased to atmospheric pressure and the coated substrate products having improved abrasion-resistance are removed from the chamber. These coated products may be plastic sunglass lenses, ophthalmic lenses, bar codes scanner windows, and indus-trial wear parts needing protection from scratches and abrasion.

IPC: A61F2/86
Filed: 1995-04-10
Abstract: A body compatible stent is formed of multiple fila-ments arranged in two sets of oppositely directed helical windings interwoven with one another in a braided config-uration.  Each of the filaments is a composite including a central core (24) and a case (26) surrounding the core (24). In the more preferred version, the core is formed of a ra-diopaque and relatively ductile material, e.g. tantalum or platinum.  The outer case (26) is formed of a relatively re-silient material, e.g. a cobalt/chromium based alloy.  Favor-able mechanical characteristics of the stent are determined by the case (26), while the core (24) enables in vivo imag-ing of the stent.  The composite filaments are formed by a drawn filled tubing process in which the core (24) is inserted into a tubular case (26) of a diameter substantially more than the intended final filament diameter.  The composite filament is cold-worked in several steps to reduce its diameter, and annealed between successive cold-working steps.  After the final cold working step, the composite filament is formed into the desired shape and age hardened. Alternative composite filaments employ an intermediate barrier layer (86) between the case (26) and core (24), a biocompatible cover layer surrounding the case (26), and a radiopaque case (26) surrounding a structural core (24).
